Combination head-protective helmet and thermal imaging apparatus
First Claim
1. Combination head-protective helmet and thermal imaging apparatus, for being worn by a person in a heated environment where stratified heat is present which increases vertically, comprising:
- a head-protective helmet including a cap and a brim circumscribing said cap and extending downwardly and outwardly from said cap sufficiently to provide an envelope of reduced heat under said brim upon said head-protective helmet being present in said stratified heat;
thermal imaging apparatus including an infrared sensor camera for producing an infrared image of a scene or object and display apparatus which generates a visible image of said scene or object from said infrared image for viewing by the eyes of a person wearing said combination;
first mounting means for mounting said camera to said head-protective helmet substantially underneath said brim to protect said camera from falling objects striking said helmet and to cause said camera to substantially reside in said envelope of reduced heat to reduce the influence of said heated environment on said camera, said first mounting means mounting said infrared sensor camera to said head-protective helmet to locate said infrared sensor to the side of the face of said person wearing said combination; and
second mounting means for mounting said display apparatus to said helmet in a position to permit the eyes of said person to see said visible image.
